Sure! Here's a simple text-based game in a single HTML file that you can play on a smartphone. Since you mentioned using pictograms, I'll represent Goku and Spider-Man using emojis. Note that this game is just a basic example and not a complete game.
To play this game, simply open the HTML file in a web browser on your smartphone. The game will display Goku and Spider-Man emojis on the screen. Press the spacebar or tap anywhere on the screen to make Goku fight Spider-Man. The game will log the outcome of the fight in the browser console and display the current score. If Spider-Man wins, the game will end, and you can refresh the page to play again.
